Delete UPM Cache #28
Description
When developing packages, it's sometimes helpful clear all caches that Unity Package Manager stores on a system.
Issue causes:
- Somebody (incorrectly) deletes a package version from a custom registry, then republishes the same version number. Now all clients must delete all caches to receive the new package or they might face PacMan errors.
- When switching git revisions in a repo, Unity Library state can sometimes get corrupted (old and new package versions fighting), this requires clearing the project package cache.
Cache locations:
- In a project
- On the computer (multiple cache locations) https://docs.unity3d.com/6000.3/Documentation/Manual/upm-cache.html
- Optionally, support custom cache location: https://docs.unity3d.com/6000.3/Documentation/Manual/upm-config-cache.html
